Review: Does what it’s supposed to - Way cheaper than OEM and works just as well
Review: Perfect replacement for my Pentair system - As happens about every five years or so, the probe that reads the water temperature for my pool goes out and starts generating wildly inaccurate readings. This two pack of sensors (which also work for the air temperature reading) were a good price, well packaged, and easy to install. My Pentair Easytouch system is pretty simple to work with and well labeled, so it is pretty straight forward to trace the wiring back to the screw terminals on the control panel. In about ten minutes, I had the old probe removed, this new one installed, and my pump back up and running. Confirmed the temperature readings of the water in both my pool and hot tub against a couple of digital thermometers that agreed within about 1 degree of each other.

### ⭐⭐⭐⭐⭐ Great replacement for Pool Pilot
*by D***D on November 27, 2025*

Worked very well replacing an original Pool Pilot sensor. Just had to add an extra gasket to prevent leakage.
